FIG. 6 shows an example of a look-up table to implement at least one example embodiment of an image resolution modification scheme, arranged in accordance with at least some embodiments described herein. Reference may be made to the embodiments depicted and described with reference to FIGS. 1-5.

As depicted in FIG. 6, a first column 610 may indicate a type of an identified subject of one or more images; second and third columns 620 to 630 may indicate a resolution usage history data for a high resolution value and a low resolution value, respectively, regarding the type of the identified subject; and a forth column 640 may indicate a preferred resolution value based on the resolution usage history data. Further, rows 650-670 may indicate how to determine the preferred resolution value corresponding to each type of the identified subjects based on the resolution usage history data.

In some embodiments, the look-up table may be stored in at least one of a resolution usage history database of user device 110 or a resolution usage history database of server device 130. Further, the look-up table may be referenced by resolution determination unit 230 of user device 110 and/or resolution determination unit 330 of server device 130 to determine the preferred resolution value for the image based on the identified subject. In accordance with one non-limiting example, when the one or more images regarding a identified subject has been stored more frequently at the high resolution value, user device 110 (for example, resolution modification unit 230) and/or server device 130 (for example, resolution modification unit 330) may determine the preferred resolution value for the image as the high resolution value. On the other hand, when the one or more images for a identified subject have been used more frequently at the low resolution value, user device 110 (for example, resolution modification unit 230) and/or server device 130 (for example, resolution modification unit 330) may determine the preferred resolution value for the image as the low resolution value. For instance, if a portrait A of portrait type 650 has been used 240 times at the high resolution value and has no record for the low resolution value, the preferred resolution value for the portrait A of portrait type 650 may be determined as the high resolution value. Further, if a portrait B of portrait type 650 has been used 1 time at the high resolution value and 10 times at the low resolution value, the preferred resolution value for the portrait B of portrait type 650 may be determined as the low resolution value.

As such, user device 110 and/or server device 130 may be able to determine the preferred resolution value with reference to the look-up table. One skilled in the art would appreciate that the type of the identified subjects and the resolution values for determination illustrated in the look-up table are non-limiting example parameters and any other parameters to implement the image resolution modification scheme in accordance with multiple embodiments described here will be available for the look-up table.

Reference may be made to the embodiments depicted and described with reference to FIGS. 1-5.

As depicted in FIG. 7, a first column 710 may indicate a type of an identified subject; and second column 720 may indicate a user setting data that a user set up as a preferred resolution value for each type of the identified subjects. Further, rows 730-750 may indicate the user setting data for the type of the identified subjects, respectively.

In some embodiments, the look-up table may be stored in at least one of a user setting database of user device 110 or a user setting database of server device 130. Further, the look-up table may be referenced by resolution determination unit 230 of user device 110 and/or resolution determination unit 330 of server device 130 to determine the preferred resolution value for the image based on the identified subject. In accordance with one non-limiting example, when the preferred resolution value for the type of the identified subject has been set up by the user as a high resolution value, user device 110 (for example, resolution modification unit 230) and/or server device 130 (for example, resolution modification unit 330) may determine the preferred resolution value for the image as the high resolution value. For instance, if the preferred resolution for a portrait A of portrait type 730 has been set up as the high resolution value, the preferred resolution value for the portrait A of portrait type 730 may be determined as the high resolution value.

As such, user device 110 and/or server device 130 may be able to determine the preferred resolution value with reference to the look-up table. One skilled in the art would appreciate that the type of the identified subject and the resolution values for determination illustrated in the look-up table are non-limiting example parameters and any other parameters to implement the image resolution modification scheme in accordance with multiple embodiments described here will be available for the look-up table.

FIG. 8 illustrates computer program products 800 that may be utilized to provide an image resolution modification scheme, arranged in accordance with at least some embodiments described herein. Computer program product 800 may include a signal bearing medium 810. Signal bearing medium 810 may include one or more instructions 820 that, when executed by, for example, a user device and/or a server device, may provide the functionality described above with respect to FIGS. 1-7. By way of example, but not limitation, instructions 820 may include: one or more instructions for identifying a subject of an image; one or more instructions for determining a resolution value for the image based, at least in part, on the identified subject; or one or more instructions for modifying a resolution of the image in accordance with the determined resolution value. Thus, for example, referring to FIG. 5 and/or FIG. 6, user device 110 and/or server device 130 may undertake one or more of the blocks shown in FIG. 5 and/or FIG. 6 in response to instructions 820.

In some implementations, signal bearing medium 810 may encompass a computer-readable medium 830, such as, but not limited to, a hard disk drive (HDD), a compact disk (CD), a digital versatile disk (DVD), a digital tape, memory, etc. In some implementations, signal bearing medium 810 may encompass a recordable medium 840, such as, but not limited to, memory, read/write (R/W) CDs, R/W DVDs, etc. In some implementations, signal bearing medium 810 may encompass a communications medium 850, such as, but not limited to, a digital and/or an analog communication medium (e.g., a fiber optic cable, a waveguide, a wired communications link, a wireless communication link, etc). Thus, for example, computer program product 800 may be conveyed to one or more modules of user device 110 and/or server device 130 by an RF signal bearing medium 820, where the signal bearing medium 820 is conveyed by a wireless communications medium 850 (e.g., a wireless communications medium conforming with the IEEE 802.11 standard).

FIG. 9 is a block diagram illustrating an example computing device that may be utilized to provide an image resolution modification scheme, arranged in accordance with at least some embodiments described herein. In these examples, elements of computing device 900 may be arranged or configured for a user device. In a very basic configuration 902, computing device 900 typically includes one or more processors 904 and a system memory 906. A memory bus 908 may be used for communicating between processor 904 and system memory 906.

Depending on the desired configuration, processor 904 may be of any type including but not limited to a microprocessor (μP), a microcontroller (μC), a digital signal processor (DSP), or any combination thereof. Processor 904 may include one or more levels of caching, such as a level one cache 910 and a level two cache 912, a processor core 914, and registers 916. An example processor core 914 may include an arithmetic logic unit (ALU), a floating point unit (FPU), a digital signal processing core (DSP Core), or any combination thereof. An example memory controller 918 may also be used with processor 904, or in some implementations memory controller 918 may be an internal part of processor 904.

Depending on the desired configuration, system memory 906 may be of any type including but not limited to volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.) or any combination thereof. System memory 906 may include an operating system 920, an application 922, and program data 924.

Application 922 may include an image resolution modification algorithm 926 that may be arranged to perform the functions as described herein including the actions described with respect to a user device architecture as shown in FIG. 2 including the actions described with respect to the flow chart shown in FIG. 4. Program data 924 may include any data that may be useful for providing the image resolution modification scheme as is described herein. In some embodiments, application 922 may be arranged to operate with program data 924 on an operating system 920 such that the scheme for modifying a resolution of an image as described herein may be provided.

Computing device 900 may have additional features or functionality, and additional interfaces to facilitate communications between basic configuration 902 and any required devices and interfaces. For example, a bus/interface controller 930 may be used to facilitate communications between basic configuration 902 and one or more data storage devices 932 via a storage interface bus 934. Data storage devices 932 may be removable storage devices 936, non-removable storage devices 938, or a combination thereof. Examples of removable storage and non-removable storage devices include magnetic disk devices such as flexible disk drives and hard-disk drives (HDD), optical disk drives such as compact disk (CD) drives or digital versatile disk (DVD) drives, solid state drives (SSD), and tape drives to name a few. Example computer storage media may include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data.

System memory 906, removable storage devices 936 and non-removable storage devices 938 are examples of computer storage media. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which may be used to store the desired information and which may be accessed by computing device 900. Any such computer storage media may be part of computing device 900.

Computing device 900 may also include an interface bus 940 for facilitating communication from various interface devices (e.g., output devices 942, peripheral interfaces 944, and communication devices 946) to basic configuration 902 via bus/interface controller 930. Example output devices 942 include a graphics processing unit 948 and an audio processing unit 950, which may be configured to communicate to various external devices such as a display or speakers via one or more A/V ports 952. Example peripheral interfaces 944 include a serial interface controller 954 or a parallel interface controller 956, which may be configured to communicate with external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device, etc.) or other peripheral devices (e.g., printer, scanner, etc.) via one or more I/O ports 958. An example communication device 946 includes a network controller 960, which may be arranged to facilitate communications with one or more other computing devices 962 over a network communication link via one or more communication ports 964.

The network communication link may be one example of a communication media. Communication media may typically be embodied by computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as a carrier wave or other transport mechanism, and may include any information delivery media. A “modulated data signal” may be a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media may include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, radio frequency (RF), microwave, infrared (IR) and other wireless media. The term computer readable media as used herein may include both storage media and communication media.

Computing device 900 may be implemented as a portion of a small-form factor portable (or mobile) electronic device such as a cell phone, a personal data assistant (PDA), a personal media player device, a wireless web-watch device, a personal headset device, an application specific device, or a hybrid device that include any of the above functions. Computing device 900 may also be implemented as a personal computer including both laptop computer and non-laptop computer configurations.

The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation, no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general, such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, etc. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, etc As will also be understood by one skilled in the art all language such as “up to,” “at least,” and the like include the number recited and refer to ranges which can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

From the foregoing, it will be appreciated that various embodiments of the present disclosure have been described herein for purposes of illustration, and that various modifications may be made without departing from the scope and spirit of the present disclosure. Accordingly, the various embodiments disclosed herein are not intended to be limiting, with the true scope and spirit being indicated by the following claims. 

1. A method performed under control of one or more processors, the method comprising: identifying a subject of an image; determining a resolution value for the image based on one of a resolution usage history database and a user setting database, wherein the resolution usage history database includes resolution usage history data that corresponds to the identified subject, and wherein the user setting database includes a preferred resolution value that corresponds to the identified subject; and modifying a resolution of the image based on the determined resolution value. 2-26.
